Patented Feb. 16, 1937 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in venereal air syringes and the principal object of my invention is to provide a syringe designed to be used in the treatment and prevention of diseases.

Another object of my invention is to provide a syringe which can be used in the furtherance of medical treatment necessitating the flushing of the uterus or body and which provides a means for releasing the air when the treatment is com-v lO pleted.

The objects and advantages are attained by the construction illustrated in the accompanying drawing, wherein,

Fig. l is a side view of my syringe.

Fig. 2 is an enlarged vertical section of a portion of my invention.

Similar reference characters refer to similar or like parts throughout the drawing.

Now referring to the drawing it will be found 20 that my invention comprises a rubber bulb 2,

which may be round as shown or of any other suitable shape, said bulb having outlets or necks 3 and 4. Within said neck 3 is a suitable check valve c and tted over the exterior of said neck g5 is a nipple 5 adapted to be placed in a receptacle containing the solution to be used when it is desired to fill the bulb 2. The neck 4 is fitted tight over a fitting f which forms a part of a three way valve 6 and contained within said :so iitting f is a suitable check valve di Again referring to the drawing it will be seen that there is also attached to said valve t through the use of proper ttings such as h and 9'2 a syringe tube l and air vent tube 8, said syringe tube l', 35 which is used for conveying the solution during treatment, being of uniform diameter and curved so it can easily be inserted into the uterus, and having at its extreme end small openings m for the release of the solution. Air vent tube 8 which 40 is used as an air vent is curved as shown and suitably adhered to syringe tube l at a point designed by k forming a handle.

In the use of my venereal air syringe I turn my control valve to a position as shown in Fig.

v 45 l, usingthe member p for this purpose, this opening the passage from the bulb 2, valve 8 and syringe tube l, all the air is then released by compressing the bulb and the nipple 5 placed in the solution to be used, the bulb is then re- 50 leased causing a vacuum which opens the check valve c allowing for the reception of the solution into the bulb after which the said check (Cl. 12S- 232) valve c closes and the said valve B is then turned to the position shown in Fig. 2 to prevent the solution from escaping while the syringe is being placed. The syringe tube 1 is then inserted after which the valve is turned to the position shown in Fig. l, opening the passage between the bulb 2 and the syringe tube l excepting for the check valve d which remains closed thereby retaining the solution in the bulb. The bulb 2 is then compressed thus opening the check valve d and forcing the solution through the valve openings and syringe tube l to the part or parts to be treated. After the solution remains a short time in the parts being treated it is sometimes desirable to compress the bulb and release the Same severa] times thus causing blasts of air to thoroughly cleanse out the part or parts being treated after which the air must be released. To accomplish this release of air I turn my valve to the position shown in Fig. 2 thereby closing the passage between the bulb and tube l and opening the passage through syringe tube l, valve 6 and the air vent 8 thereby allowing the natural contraction of the treated parts to expel trapped What I claim:

A venereal air syringe, having in combination a syringe tube of uniform diameter the entire length and curved to permit its insertion into the uterus, small openings at the outer end of said syringe tube, the opposite end being open, a rubber bulb having necks with openings at opposite positions, the outer neck having engaged thereon and connected therewith a nipple having a central passage and openings at each end, check valves in said necks, which will permit flow through the nipple into the bulb, when a vacuum is created Within said bulb, and from the bulb, when compressed, through the inner neck to the parts to be treated and which will prevent return now to the bulb, an air vent tube, open at both ends, shaped to provide a handle for the syringe and adhered to the syringe tube, and a three way valve having said inner neck of the bulb and inner end of the syringe tube connected with it at opposite openings and said air vent tube connected at the side thereof, Valve control means for opening and closing a valve passage between the bulb and syringe tube and a valve passage between the air vent tube and syringe tube.
